postpartum preeclampsia

I’m not sure if I’m experiencing this or not but I’m about 3 days pp and last night I start being able to feel my pulse in my neck and in my ears… when trying to lay down it feel a little scary to even fall asleep bc my chest is beating so hard... I kinda have a headache but don’t and I did check my bp 144/96 and a couple other times one being 155/102 and the other only 133/88 so I’m not sure if my bp cup inaccurate but it is brand new. Please tell me some thing I should be looking out for… my feet have been swollen but dr said that would be normal after baby
